Question

For voice analysis, the exhibits are forwarded to ______________________________ division of the Forensic Science Laboratory.

• A. Chemistry
• B. Physics
• C. Ballistics
• D. Documents

Hint:

Think about the fundamental nature of the evidence. A voice is sound, and sound is a physical wave. Therefore, voice analysis belongs to the \textbf{Physics} division.

Answer 1

The Correct Option is B

Step 1: Understand voice analysis. Voice analysis (forensic phonetics or speaker identification) involves the scientific analysis of speech sounds. It deals with physical properties of sound waves like frequency (pitch), amplitude (loudness), and spectral characteristics (voice quality or timbre).

Step 2: Relate to scientific disciplines. The study of sound waves and their physical properties is a fundamental branch of Physics. Forensic physics divisions in laboratories handle a variety of evidence types involving physical measurements, including acoustics (sound), optics (glass), and mechanics (tool marks).

Step 3: Evaluate other options. Chemistry deals with substances and chemical reactions. Ballistics deals with firearms. Documents division deals with handwriting and print. The Physics division is the most appropriate for analyzing the physical characteristics of a voice recording.
